Connection Problems
When an access point is converted from standalone AP mode to managed AP mode, its
static IP address is changed to an IP address that is issued by the DHCP server, either one in
the network or one that is configured on the wireless controller. This occurs to ensure that
each managed access point has a unique IP address.
If there is no DHCP server or if the access point cannot reach the DHCP server, the access
point remains in the Connecting state, attempting to obtain an IP address. If there is no
DHCP server in the network, configure one on the wireless controller (see Manage the DHCP
Server on page 51). When a DHCP server becomes available, the access point can
transition from the Connecting state to the Connected state.
Network Performance and Rogue Access Point Detection
When rogue access point detection is enabled, access points intermittently go off channel for
short periods, which can affect network performance. The default rogue access point
detection interval is 30 minutes. This interval is not configurable.
Use the Diagnostic Tools on the Wireless Controller
As part of the diagnostics functions on the wireless controller, you can ping a managed
access point from the wireless controller or trace its route from the wireless controller.
 To ping an access point:
1. Select Diagnostics > Ping.
The Ping screen displays:
